Does PlayBook Has Sim Card Slot?

i wonder does playbook have sim card slot like Samsung Tab?
i want to use my BiS activated Sim card on my PlayBook and use it with my wired headset or bluetooth.
Make Phone calls,send/receive text messages, bbm,facebook etc.
Will it be possible ?

From what I understand, when you hook your BB up to the PB, you'll be able to send messages/BBM/texts using your BB's carrier/plan, so you can see the message in a bigger screen. I would assume no phone calls though, might be a bit awkward to talk on a tablet. As for Facebook, you'll be able to access that through the internet and the FB app.
